After hours and still working!
Some evenings, especially during my first year of the Peace Corps, I would help serve in the school cafeteria where I was a teacher. The students always got a kick out of me helping prepare the food, serve it, and especially clean up at the end of the meal. I learned that when you have mess hall duty, you have to shovel your own plate down as fast as you can to get right back to work behind the serving counter. I always had a great time speaking English with students who were not mine and learning Portuguese or Changan slang that the "kids" spoke to one another.
